THOMAS H. OONLEY, OF WARE, MASSACHUSETTS.

SPlNNlNG-MULE.

SPECIFICATION forming part of Letters Patent No. 382,139, dated May 1,1888.

Application filed January 30, 1888. Serial No. 262,353. (No model.)

To all whom, it may concern:

Be it known that I, THOMAS H. CONLEY, of Ware, in the countyof Hampshireand State of Massachusetts, have invented certain new and usefulImprovements in Spinning-Mules,'

of which the following is a specification.

It is the object of my invention to provide improved means of bandingthe operative parts of a spinning-mule, particularly that class of mulescommonly known to spinning artisans as the Mason mule, as exemplified inUnited States Letters Patent No. 4,779, dated October 3, 1846.

My invention consists in the improved means, hereinafter described andclaimed, whereby that portion of the copping mechanism embraced in thebacking off and winding devices on both sides of the mule-head may bedriven by a single band.

As is well known to mule operatives, the backing offand winding devicesof the coppiug mechanism on the opposite sides of the head of a Masonmule are driven by independent bands, while the two driving-pulleys,which give motion to such independent bands, are operated by a commonmotor at a uniform rate of speed, so that any variation in the bandingresults in a variation in the character of the yarn spun on the twosides of the head, as also in waste of material, loss of time, and otherdifficulties and objections. It is also well known that it isexceedingly difficult, and, in some instances, next to impossible, toavoid variation in banding- -as, for example, where a new orcomparatively new band is used on one side and an older band on theother, or where the two bands are put on with different degrees oftightness. These variations, though they may be slight in themselves,result in serious variations and defects in the manufac ture of yarn bythe mule, among which are frequent breaking and consequent waste of yarnin backing off and winding up, lack of uniformity in the character ofthe cops, those on one side being comparatively soft, while those on theother side are much harder, and lack in uniformity of twist put into theyarn. These objections and disadvantages are overcome by myimprovement,.and I am, besides, enabled to operate the mule withsteadier motion, and effect a substantial saving in rim and spindlebanding, and in the power required to operate the mule, since a singleband can be run much slacker in the production of good work than can twoindependent bands; and, besides this, it requires less skill to adjustone band than two, and requires less labor to properly care for one bandthan two, since a single band does not have to be kept so tight on thepulleys as two independent bands, and is therefore not so liable to slipor be subjected to the same extent of wear.

My invention will first be described in connection with the accompanyingdrawings and the letters of reference marked thereon, form ing a part ofthis specification, and subse quently pointed out in the claim heretoappended.

Of the drawings, Figure 1 is a top. plan view of my improvements. thesame. Fig. 3 is a side view of the old and common means of handing.

The same letters of reference designatethe same parts in all of theviews.

Fig. 2 is a side view of I have not shown any of the mechanism. of

the mule-head, or of that connected with the carriage, save the pulleysor rims around which the rim band passes, as this is all of saidmechanism that it is necessary to illustrate in order to give a full andcomplete understanding of my improvement, and information sufficient toenable others skilled in the art of mule-spinning to make and use thesame.

In the drawings, a designates the frame of be seen, are not onlyemployed in connectionwith my improvements, illustrated in Figs. 1 and2, but are common to the old and wellknown banding devices, as shown inFig. 3.

Though there is no representation in Fig. 1 of carriage b or its pulleyse f, it will be understood of course that there are such devices on bothsides of the head which may be supposed to be comprised within the framea.

6 designate band-guiding pulleys supported on the frame a,-though itwould answer as well if they were independently supported, whichband-guiding pulleys are so arranged as that a single band, B, passingover the pulleys c, d, e, f, g, and h on one side of the head may bedirected or guided to proper position on the other side, to be passedover like pulleys thereat, and returned to the first-mentioned side,whereby said single band B may be made to drive the operating mechanismon both sides of the head.

The arrows marked on the drawings in close proximity to the band Bindicate its course of travel in the machine. Starting from the point 3,for example, said band passes around pulley c, thence aroundwinding-pulley d, thence around band-tightening pulley g, thence aroundpulleys e f on the carriage, thence around pulley h, to and aroundhorizontally -arranged guidepulley 13, crossing to and passing aroundguide-pulley j, and around pulleys on the op posite side of the head,corresponding to the pulleys 0, d, e, f, g, and h, before described,back to pulley j, and around the same, crossing to and passing aroundpulley i, and leading back to the point 3, at which it was presumed thestart was made. In this way I am enabled to operate the portion of thecopping mechanism mentioned on both sides of the head, with a singleband and in unison, accomplishing the objects and attaining the ends setforth at the outset of this specification.

Having thus explained the nature and objects of my invention, what Iclaim is- The combination, with a dual set of rims or pulleys in aspinning-mule, each set consisting THOMAS H. CONLEY.
